New Avenues for = 2 Processes Beyond Neutron-Antineutron Oscillations
Arnau Bas i Beneito, Svjetlana Fajfer, Alexey A. Petrov
We explore baryon-number-violating () processes beyond the well-known neutron-antineutron () oscillations, focusing on the system. The presenc…
EFT Pathways to : Chiral Constructions and Phenomenology
Arnau Bas i Beneito, Ajdin PalavriÄ, Andrea Sainaghi
We develop a systematic effective field theory framework for studying interactions across energy scales. Using chiral symmetry, we construct the complete and non-redundan…
Implications of Flavor Symmetries for Baryon Number Violation
Arnau Bas i Beneito, Ajdin PalavriÄ, Andrea Sainaghi
In the Standard Model, baryon number is an accidental symmetry, whose violation would constitute unambiguous evidence of new physics, with proton decay providing its most prominent…
Squeezing Proton Decay and Neutrino Masses: Upper Bounds on Standard Model Extensions
Arnau Bas i Beneito, John Gargalionis, Juan Herrero-Garcia +1
Baryon and lepton number are excellent low-energy symmetries of the Standard Model (SM) that tightly constrain the form of its extensions. In this paper we investigate the possibil…
Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics
Leah J. Broussard, Andreas Crivellin, Martin Hoferichter +19
Processes that violate baryon number, most notably proton decay and transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the…
